Prescriptive process model were originally proposed to bring order to the chaos of software development. Prescriptive process model define a prescribed set of process elements and a predictable process work flow. “prescriptive” because they prescribe a set of process elements framework activities, software engineering actions, tasks, work products, quality assurance, and change control mechanisms for

In order to build software engineering a layered technology that is ready to meet the challenges of the twenty first century, you must recognize a few simple realities. Problem should be understood before software solution is developed Design is a pivotal Software Engineering activity Software should exhibit high quality Software should be maintainable These simple

In the early days of the World Wide Web, websites consisted of little more than a set of linked hypertext files that presented information using text and limited graphics. As time passed, the augmentation of HTML by development tools (XML, Java) enabled Web engineers to provide computing capability along with informational content. Web based systems

Software takes Dual role of Software and Software Engineering. It is a Product and at the same time a Vehicle for delivering a product. Software delivers the most important product of our time is called information. Defining Software Software is defined as :- 1. Instructions : Programs that when executed provide desired function, features, and

A const member function guarantees that it will never modify any of its class’s member data. The CONSTFU program shows how this works. //constfu.cpp //demonstrates const member functions / class aClass { private: int alpha; public: void nonFunc() //non-const member function { alpha = 99; } //OK void conFunc() const //const member function { alpha

Having said that each object contains its own separate data, we must now amend that slightly. If a data item in a class is declared as static, only one such item is created for the entire class, no matter how many objects there are. A static data item is useful when all objects of the

We’ve seen two ways to initialize objects. A no-argument constructor can initialize data members to constant values, and a multi argument constructor can initialize data members to values passed as arguments. Let’s mention another way to initialize an object: you can initialize it with another object of the same type. Surprisingly, you don’t need to

We mentioned that inline function save memory space because all the calls to the function cause the same code to be executed; the function body need not be duplicated in memory. When the compiler sees a function call, it normally generates a jump to the function. At the end of the function it jumps back

The existence of functions makes possible a programming technique called recursion. Recursion c++ involves a function calling itself. This sounds rather improbable, and indeed a function calling itself is often a bug. However, when used correctly this technique can be surprisingly powerful. Recursion is much easier to understand with an example than with lengthy explanations,
